IPC: B60G17/00
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To improve mountability of a pressure source for adjusting the height of a vehicle to a car body by incorporating it integrally with the damper, and to obtain a leveling function without using a special control mechanism. SOLUTION: A case 9, which is connected with a damper rod 2 and can be moved freely in the upward or downward direction, is installed outside a damper body 1, and a pressure chamber 10, in which a pressure medium changing reciprocally from a vapor phase to a liquid phase is sealed tightly, is formed between the damper body 1 and the case 9. Also, a heating chamber 14 is formed on the circumferential wall of the damper body 1, and the pressure medium is heated and vaporized by running a heat medium, and then the damper rod 2 is raised against the damper body 1 by an increase of the internal pressure of the pressure chamber 10, to thereby raise the height of a vehicle.  In this case, an overlapped length between the pressure chamber 10 and the heating chamber 14 is decreased following the raise of the case 9, and the entering heat amount is decreased, and consequently when the height of the vehicle reaches a certain level, it is maintained at the same level. Also, the height of the vehicle can be changed at plural steps, by dividing the heating chamber 14 into at least two, namely, upper and lower chambers, 14H and 14L, and by switching the situation in which the heat medium is run only in the lower chamber 14L to the situation in which it is additionally run in the upper chamber 14H, too.

Abstract: PURPOSE:To change the reference voltage corresponding to the deterioration of a light emitting element with the passage of time by obtaining the reference voltage directly from the detected light of the light emitting element through a light receiving element wherein the light emitting element is composed of sole light emitting diodes. CONSTITUTION:Slits 12 are formed in the circumferential direction at a constant distance in a rotary disk 2 and a light emitting element 4 is composed of sole light emitting diodes. Meanwhile, a light receiving element 8 has light receiving regions 18, 20 for signals from which respective A and B-phase signals are sent and a light receiving region 22 for reference voltage from which the reference voltage is sent. In the element 8, the region 22 is extended to the circumferential direction on a center, the rotary axis of the disk 2, and receives the light to be detected which is the light emitted from the element 4 and intensified by times of one cycle of the light distribution by the slits 2. In this way, since the element 4 is composed of sole diodes, the A-phase and B-phase signal voltages do not change individually and also since the light to be detected which passes the slits and quantity of which alters periodically corresponding to the rotation speed of the disk 2 is received by the region 22 and the reference voltage is obtained directly, the reference voltage also alters corresponding to the deterioration with the passage of time of the element 4.

Title: Electromagnetic flowmeter
Inventor: TOMITA TOYOFUMI
IPC: G01F1/58
Filed: 1989-10-25
Abstract: PURPOSE:To save the power and to miniaturize the flowmeter by calculating the difference between the output of an electrode when the magnetic field of a permanent magnet is applied to a conduit vertically through a 1st magnetic path, and the output signal of the electrode when the magnetic field of the permanent magnet is not applied to the conduit through a 2nd magnetic path, and finding a mean flow velocity from the result. CONSTITUTION:When magnetic fluid 15 is magnetized at right angles to the magnetic field (m) of the permanent magnet 14, the magnetic field (m) is applied to a core 16 together with the magnetic field (d) of an exciting coil 14, a magnetic field reaching a coil 12 becomes weak, and a magnetic field applied to the conduit 11 becomes small. Therefore, the electromotive output that the electrode 21 detects becomes small and only a polarizing voltage signal which is stored in the electrode 21 is taken out and charged in a capacitor 25 while a switch 26 is on. Then a differential amplifier 27 amplifies the difference between charges in capacitors 23 and 25 to output a signal (h) which is proportional to the mean flow velocity of the conductive fluid flowing in the conduit 11.
